Prefabricated assembly type shear wall having damping function

Abstract

The invention discloses a prefabricated assembly type shear wall having a damping function. The prefabricated assembly type shear wall is characterized in that an energy dissipation and seismic-reduction component composed of a shear type soft steel damper, an edge steel structure, a lower connecting plate and an upper connecting plate is arranged in a prefabricated shear wall building structure. The lower connecting plate is arranged on a lower floor prefabricated shear wall and fixedly connected with lower edge component longitudinal bars and lower shear anchor bolts of the lower floor prefabricated shear wall. A plurality of upper edge component longitudinal bars, upper non-edge component longitudinal bars and upper shear anchor bolts, which are fixedly connected with an upper floor prefabricated shear wall, are reserved on the upper connecting plate. Compared with the prior art, the prefabricated assembly type shear wall is good in energy dissipation and seismic-reduction performance, the anti-seismic property of the shear wall building structure is improved, the energy dissipation and seismic-reduction problems of assembling integral shear wall structures are solved well, and the prefabricated assembly type shear wall is particularly suitable for popularization and application in high-rise buildings in high intensity seismic areas.

Description

Technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated shear wall with damping. Background technique [0002] The assembled monolithic shear wall structure is constructed using factory-prefabricated shear walls and other components and nodes cast-in-place, which has broad application prospects. Due to the certain difference between the construction process and the cast-in-place structure, it is safer under earthquakes. Eye-catching. The energy dissipation and damping technology of building structure is to increase structural damping by installing energy dissipators in the building structure or design some support or shear wall components as energy dissipation components, so as to reasonably control the structure of the engineering structure under the action of earthquake and wind In response, studies have shown that energy dissipation technology can cost-effectively improve the seismic performance of structure...

AI Technical Summary

Problems solved by technology

[0003] At present, the prefabricated integral shear walls under construction usually do not have energy-dissipating and shock-absorbing components. Under strong earthquakes, energy is dissipated through cracking and plastic deformation of the coupling beams and shear walls. These damages are irreparable.
